Check Digit Verification of cas no

The CAS Registry Mumber 158205-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,2,0 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 158205-48:
(8*1)+(7*5)+(6*8)+(5*2)+(4*0)+(3*5)+(2*4)+(1*8)=132
132 % 10 = 2
So 158205-48-2 is a valid CAS Registry Number.

TOTAL SYTHESIS OF ISLANDIC ACID I METHYL ESTER, ROSELLISIN AND ROSELLISIN ALDEHYDE

Shimizu, Takeshi,Hiranuma, Sayoko,Watanabe, Tsumoru,Kirihara, Masayuki

, p. 243 - 248 (1994)

Total synthesis of islandic acid I methyl ester (2), rosellisin (3) and rosellisin aldehyde (4) has been accomplished starting from 4-hydroxy-5-hydroxymethyl-6-methyl-2H-pyran-2-one (9a) via formylation of 9a with dichloromethyl methyl ether and titanium tetrachloride as a key step.
