Check Digit Verification of cas no

The CAS Registry Mumber 58253-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,2,5 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58253-89:
(7*5)+(6*8)+(5*2)+(4*5)+(3*3)+(2*8)+(1*9)=147
147 % 10 = 7
So 58253-89-7 is a valid CAS Registry Number.

STEREOSELECTIVITY AT BENZYLIC CARBON. FLAVANOIDS-V. SYNTHESIS OF TRANS-4-ACETAMIDOFLAVANS

Hirwe, A.,Marathe, K. G.,Mohorkar, S. S.,Ramdas, K.,Singh, C. B.

, p. 1539 - 1546 (2007/10/02)

Some reactions of 4-substituted flavans have been studied. 4-Chloro/bromo derivatives react under neutral conditions with phthalimide and acetonitrile leading to displacement of axial halogen by nitrogen with inversion.In contrast, irrespective of the ste
