Check Digit Verification of cas no

The CAS Registry Mumber 75630-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,3 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75630-48:
(7*7)+(6*5)+(5*6)+(4*3)+(3*0)+(2*4)+(1*8)=137
137 % 10 = 7
So 75630-48-7 is a valid CAS Registry Number.

Biosynthesis of Porphyrins and Related Macrocycles. Part 13. Structure of the Protoporphyrin Isomer derived from Coproporphyrinogen lV by the Action of Beef-Liver Coproporphyrinogenase: Synthesis of Protoporphyrin Xlll

Battersby, Alan R.,Hamilton, Andrew D.,McDonald, Edward,Mombelli, Luisa,Wong, Oi-Hoong

, p. 1283 - 1289 (2007/10/02)

Coproporphyrinogen lV (8) is synthesised and is oxidatively decarboxylated by coproporphyrinogenase from beef-liver to produce, after aromatisation, a porphyrin proved to be protoporphyrin Xlll (11) by spectroscopy and by unambiquous synthesis; the synthesis route is described.A monovinylporphyrin, derived from an intermediate for the conversion (8) -> (11), is also isolated.The importance of these results for earlier biosynthetic studies with pyrromethanes is discussed.
