Check Digit Verification of cas no

The CAS Registry Mumber 125589-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,5,8 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125589-89:
(8*1)+(7*2)+(6*5)+(5*5)+(4*8)+(3*9)+(2*8)+(1*9)=161
161 % 10 = 1
So 125589-89-1 is a valid CAS Registry Number.

ETHYL N-DIENYL PYROGLUTAMATES: NOVEL ASYMMETRIC DIENES

Menezes, Royce F.,Zezza, Charles A.,Sheu, Jennline,Smith, Michael B.

, p. 3295 - 3298 (1989)

Conversion of L-glutamic acid to S-ethyl pyroglutamate allows reaction with α,β-unsaturated aldehydes to give the N-dienyl derivative.The resulting dienyl pyroglutamates are new asymmetric dienes which show excellent diastereoselectivity in the Diels-Alder reaction with electron deficient alkenes.
